Division 1.

Method of making a water-proof sheet cmd applying t to a foundationsheet.

In theA drawings F ig. 1 discloses a'ma chine A for making theWater-prooi1 sheet hereinafter described, a machine B for Water-proofingthe foundation sheet. and a machine C for joining and drying the tivosheets thus formed.

ln Fig. 1 at B, 1 is a roll of suitable paper or felt, which is, passedby any suitable means through atank'of Water-proofing material 2, aseries of rollers 3 and Ll, serving to keep the paper iii the tank asufficient length of time during its travel to thoroughly saturate itwith the Wav-terproofing compound.

A. pairof squeeze rollers 5 squeezes all surplus water-proofing compoundfrom the paper, and it then passes tothe joining rollers 6, Where it isrolled together With a sheet of waterproof and Weather-proof compound 7prepared with the machine shown at A.

This machine A consists essentially of a belt 8, preferably of metal orsome hard substance carried by the driving rollers 9,

which may be driven by any .suitabley method, the speed of the sheet 7being substantially equal to that of the paper 1.

A suitable Weather-proof and Water-prooic compound is deposited from thetank 10 to the metal belt. and is scraped to the desired thickness bythe scraper 11, or if desired a pair of rollers may be substituted toanswer the. same purpose as the scraper.

After the material has been scraped or rolled to the proper to thevibrator 14,, operated in any suitable manner, and Water from a pipe 15is applied to the top of the sheet 7, and the knife 16 .tlat against thebelt lifts the material therefrom and it is'passed over the roller 17down to' the squeeze rollers 6, Where it joins With the sheet 1, and asboth. sheets are thickness it passes` on still snciently sticky for thepurpose, they are joined together by their own body, and passing overthe rollers 18 and'19 vare dried by a'column of air from the hood 20,and reeled up at 21 to form a roll of completed materia As thepreliminary cooling was done when the water-proof sheet 7 was on thebelt 8, the lower side of 'the sheet 7 is dry at all times, and hence itis impossible for any moisture to be taken up by the sheet 1 when itiscombined with the sheet 7 by the rollers In the formation asdescribed, the reservoir 12, its deposit, and the rollers 13 are to beconsidered as removed, their function being explained in a furtherdivision of the subject.

In the machine A the distance between the rollers 9 may be any amount,possibly'.

scribed.

Also the means of cooling may be varied and the methoz shown in Fig. 11is the'one that I prefer. y

In this the belt 8 with the sheet 7 thereon passes through the rollers132 and therefrom down through the water in the tank 22, being guided byone or more rollers 52 to de- .termine the length of time they remain inthe water, and I provide pipes (lhaving jets therein to spray the outersurface of the sheet 7 and wash from it all surplus mineral material,cooling the sheet at the same time.

Passing over the guide roller 62, the sheet and belt continue to thesecond roller 9, Figs.r 9 and 11, where the sheet 7 is separate from thebelt 8, and the belt 8 continues to the rollers 9" and back to the'rstroller 9, Fig. 1;

The roller 9, Fig. 11, consists essentially of aF series of rollers 92,as shown in Fig. 12,

'which is a top view of Fig. 11 withfthe belt removed. All ofthe'sections' of the rollers are joined and driven by the same shaft andthe vibrator consists of units extending from .a common arm or shaftf63into the openings between the rollers 92 so as to vibrate'the entirecompound roller 9 at a point where the sheet 7 is bent on the belt 8around the periphery of the rollers. At this point the tendency of thesheet 7 will be to leave the belt 8. 1

The' sheet 7 having been raised from the kbelt 8 by the knife 16 thenpasses over the .ing 'tanks and paper and utilize in lieu 4thereof thespray pipe 81, Fig. 11, which sprays water against the inside of thebelt 8, thus chilling the inner surface of the sheet 7 vand causingit tocome off of the belt freely.

Ordinarily the belt 8 after the sheet 7 has been lifted therefrom passeson from the roller 9, Fig. 1, to a set of guide rollers 4 and 45"carrying the belt down into a tank of cooling liquid 22, preferablywater.

The water-proof compound deposited on the belt'from the reservoir 10 isheated, and as the metal belt is cooled the compound will shrink as itcomes into contact with the metal belt, whereas the metal belt willexpand from its contact with the hot com-pound, and

this with the rapping of the vibrator and.

the chilling of the sheet 7 by Water is, with most compounds, sufficientto allow the material to be readily lifted from the belt by the knife16, although as a further precaution, I sometimes employ soap-stone orother similar material, depositing it on the belt from the tank 2 3Fig'. 1 before the Waterproofing compound i's applied. In place of thesoap-stone, I sometimes apply a thin coating of a. hard material, suchas a mixture of mostly mineral asphalt from the tank 23, using a scrapersimilar to 11 to make the sheet very thin, and as this subst-ancebecomes very brittle when chilled the sheet of Water-proof material 7applied on to of this hard brittle sheet iseasily lifted rom the belt 8by the knife 16.

I sometimes employ as a means for insuring the free lifting of the sheet7 from the belt 8 by the knife 16,'"a sheet of thin waxed paper or cloth8, which would be carried on top of the belt 8, the materials beingdeposited on this sheet instead of directly on L the belt 8, as shown inthe Fig. l, and thisl sheet may be an endless belt running 'over rolls9, 52 and 42 through a bath of waxin the tank 221 so as to be rewaXed ateach revolution if desired. j l

The ordinary method of` Water and weather-proong the foundationisheet isto apply the coating, such as I apply from the reservoir 10,directly-onto the foundation sheet, but there are many grades of stockor paper that lwill not stand the application of a coating at ahigh-melting point vas the heat will deteriorate the stock.

It is ofcourse evident that With my,v

method of manufacture it is immaterial what themelting point of thecompound is, as it is suiciently cooled before it is'applied to alsoevident that by having a number of dif-Y ferent sets of machines, suchas A, I would .a ter at the portion 51 than at the portion 52',

be able to apply any number of coatings to a foundation sheet in acontinuous process and these coatings could be of any consistency andany melting point that I wish.

lflfatcproof sheet, formed 'with sections' of differing thickness,applz'cdto a found-ae tion sheet.

As itis sometimes desirablel in preparing roofing that 1s to be used 1nmaking shingles to have the sheet thicker in some portions than inothers, so that shingles or shingle strips may be made therefrom whereinthe bottom of the shingle strips will be thicker than the top, I utilizea variation of my method for preparing such roofing, and disclose meansherein for manufacturing roofing that will cut into shingles or shinglestrips of varying thickness in two different styles; namely, a shinglewherein the butt is thicker than the top, the thickness diminishinggradually from the butt to the top; the second where approximately'halfof the shingle at the-butt is of a uniform thickness, and the other halfat the vtop is of a uniform thirlniess that is less than that of thelower hal In forming the prepared roofing for the first style, I use apair of specially formed rollers 31, Fig. 17, in place of the rollers 9in the machine A Fig. 17 is a view, partly in section, of

.such a roller, the belt 8 and the water-proof compound formed thereon.

The belt 8 is tightly stretched so as to -follow the contour of therollers, and the waterproof compound deposited on the belt from thereservoir 10 will tend to ilow so as to seek a level, as shown in Fig.17 at 33, leav ing the compound thicker at 33 than at 322.

rIhe rollers 13 in thev machine"A will`of course tend to assist thenatural Atendency ofthe compound to seek. its level and set itself inthe shape as disclosed inthe cross section 33, and in case I am usingthe mineral coatinfr from the reservoirl, as will be describe later, Iwould use an'. additional. pair of rollers just beyond the scraper 11.

In making the second style of roofing to be cut into shingles ofdifferent thickness at different parts of the shingle, I- employ a pairof rollers similar to those disclosed in- Fig. 13, which is a sectiontaken through the axis of the two rollers, with the major portions ofthe rollers brokenaway, as the in-f tention is to show only the contourof the y suraces'of the ,rollers Theupper rolle 51 has a smallerdiameand this pair of rollers would be placed in the position on thebelt 8 in the machine A, Fig. 1, occupied by the scraperll.

I also use a scraper 11 to accomplish the same result as the rollers 51and 52, the scraper 11 used in the machine A, Fig. 1, being shown in afront View in Fig. 14, and as used to forni the different thicknesses ofwaterproofing sheet, being shown -at 11', Fig. 14:, the result beingobvious.

I also obtain the saine result by running the belt`64, Fig. 3, over thepulley 51, in this case the pulley being of uniform diameter throughout,but the belt of different thickness along different longitudinal strips,as shown in Fig. 4, which is a cross section showing the varyingthickness ofthe belt.

lVhen shingles cut from roofing sheets i,

made in this manner are laid upon a roof the appearance is as shown inFig. 23, the butt 81 of the upper shingle resting snugly in the cornerformed at g2 in the lower shingle. I

When the sheets 7 made by the machine A, Fig. 1, are combined with asheet of foundation stock 1 that has been previously prepared and is notsent through the tank of water-proofing compound 2, and in other casesthat might varise I utilize warming ovens to bring the consistency ofthe sheets to such a point that they will be readily united, oneA oven14:1, Fig. 1, being so disposed as to warm the foundation sheet; anotheroven, 142, being so disposed as' to rewarm the 'water-proof sheet 7 5and a third oven 143 being utilized tore-warm the com- 'Vpound sheet, orI may warm the rollers 6 Division IU.

Method o7' making a water-proof sheet, surfacing t with 'mineral matterand apply ng t to a foundation sheet".

By the term mineral surfacing, as used in this specification, I refer tothat surfacing often applied to prepared rooiing, which consists-offinely dividedparticles of slate, mica, sand, or any such substance, andnot to a coating of asphalt, which might technically be regarded asamineral surfacing.

In the ordinary method of manufacture where a mineral surfacing isapplied, the stock which would correspond to the paper 1, F ig.,1, has acoating of water-proof comf pound applied thereto and there is thendeposited on this'resultant sheet a mineral surfacing, which is rolledin order to embed it firmly in the Water-proof coating, and by theweightor pressure of.` the rollers on the particles of mineral matter,

often bruised or brokenthrough so as make serious defects'in the sheet,and as it is almost impossible to detect this until the the -paper is.

roofing has been in service for some time, 1t 1s one ot the most serioustroubles exper. rienced in the'manut'actu-re of mineral covered rooiinv.

This defect is entirely overcome in my method on account of the mannerlin which the mineral surfacing is applied, and constitutes a greatimprovement in the art of making mineral surfaced rooiing.

`When I make the mineral coated roofing l use the samemethod ofmanufacture, as disclosed under Division l, except that 1 then use thereservoir 12, and deposit therefrom on the sheet 7, machine A, Fig. l,the mineral surfacing and roll it into the sheet by means of the rollers13.

-Als the water-prooirl coating is then on the belt 8, which hard, thelarger particles are crushed and the rollers 13 level up the mineralsurfacing, the process continuing as explained in Division l, and thesheet 7 having the mineral surfacing thereon is rolled Form/Zag a.stifled roofing together with the foundation sheet 1 by the rollers Gwith a light pressure, giving me a mineral surfaced roofing sheet with aperfect 'foundation sheet.

M reover, if there are. any linups or knots in the foundation sl eetitselii, these Wil pass through the rollers (i, \"\\'"'hont injuringthe, paper or waterproof sheet, as no excessive pressure is required onthese rollers'.

Dcision IV.

twough the met/lod of apply/mg' the water-proof giace/,- or the mineralsurfacing.

A. considerable quantity of prepared root used at the presnt time/inmaking' design roots, either as designs on the reeling sheets, or markedby colors or otherwise, so as to form designs when the sheets are outinto shinle strips or unit shingles, and my method oi manufacture isespecially applica-ble to thisl line of the art.

ln Fig. S the foundation sheet 1 is prepared, as shown in ld, Fig. 1, orin any other composition prepared by machines similar to fr, 1, areslitted at the point 17, Fig. 1, by circular knives, shown inconventional form at 211, Fig. Q., the result being strips ot theWater-proof compound sheet, and as any desired color of Water-proofcoinpound may be nsedin the reservoir 10, Fig. 1, these strips may beslit from sheets ot' .various colors, so that the strips 1 may be red,tor instance, and the-strips 2, blue, and they are, then combinedbyineans of the rollers with the sheet 1, as shown in Fif. 2, to formthe completed striped rooting ,I p er, as shown at 9:6, the strips beingstill sufficiently stick",7 to arnalgainate periectly their edgesuevident that the remain-ing strips suitable manner, and two sheets of'from the cutters may be extended, as shown at 27 and 28, and joined byanother pair of rollers similar to 25 to a second sheet of foundationpaper, similar to l.

slitting and the relative size of resultant strips may be varied, andanyv number of colors may be combined in this manner.

l also form a striped'rooing by applying the mineral matter tolongitudinal strips of the sheet, accomplishing this by replacing theunit D of machine A, Fig. 1, with a unit D, as disclosed in Fig. 7,which is a side elevation or the unit, Fig. 8 being a plan vienT of thebelt 53 used in the unit D.

Carried by the rollers 5l, the bolt 53 coinprises number of individualbelts 53 with spaces 5e between them. l

A reservoir 12 having openings 122 for the spaces 5d deposits mineralmatter on the composition sheet 7 in the machine A, Fig. '5. Scrapers55' throw Otl from the in-v d'vidual belts 53 an j mineral matter thatn'iight be scattered thereon.

The mineral matter on the longitpdinal strips of the sheet between theindividual belts 5J is embedded into position bythe vsqueeze rollers 13,the additional scraper 56 the belt before the second roller 54 isreached.

, metal belt 103, similar to machine A, but the machine disclosed inFig. 19 has running along the upper surface of the belt 108 a number ofthin ilat metal ribbons 115, running. the length of the belt 108, allyof them being shownV broken o, exc'ept the one marked 115', which isshown turning around a pair of mule shafts 116 at one end, and a secondpair 11'? at the other end, to indicate the manner in Which thendlessbelts would be returned, so as to always travel over the top or" thebelt 108 ina vertical position. I

A multiple reservoir 110 deliverswaterproof compound in the usualmanner, except that there are individualv spouts delivering the compoundin the channels formed bo- 45 1 run together, or the nliileral would beof d 111 scrapes off the compound in the usual other set-of similarrollers and belt is shown Way, While the multiple reservoir 112 is proin Fig. 6, having apertures 42 1n the belt vided for depositing mineralmatter, and` rollers 113 embed the mineral surfacing in the compounddeposited on the belt 108.

The metal ribbon 115 may be of considerable height, in which case therollers and the scraper would be cut out so as to allow them to passdown between the ribbons, in order to operate on the surface of theroofing sheet,

or the ribbons may be of the same height as the thickness of thecoating, in whichcase the scraper and rollers would be of the usualconstruction.

It is evident from the'machine shown in Fig. 19 that different qolors ofcompound may be delivered from the various compartments' of reservoir110, thus making striped roofing with the stripes in the compounditself, or a uniform color may be used in the compound and differentcolors of mineral surfacing applied from reservoir 112, or both of thesemethods maybe combined, the mineral surfacing being applied on colors insome of the strips, and the coloring of the strips not so covered withmineral surfacing being varied by the compound itself.

It is evident that the metal ribbons running on beyond the place wherethe sheet of compound 7 is lifted from the belt are held vertical untilthey are free from the sheet 7 Aand the turn on the mule shaft is thenmade.

. Division V.

Desz'gm'includzng stencil designs on roofing sheets and designs forshingle strips and um't shingles ont from roofmg sheets.

A great many attempts have been made in the past to form designs on theprepared roofing by applying thereto mineral surfacing materials, butthese attempts have not been entirely satisfactory in the past, as thetendency has always been for the colors to diHerent thicknesses atdifferent. parts lof the sheet, and in all cases the waste mineralmatter naturally falling from the sheet in -the process 4would consist,of different' colored substances mixed together, which of course couldnot be used again.

In one variation of my' improved 'method of making mineralllsurfa'cedrooling, I employ lunits G and,` I-I. Unit G consists of an endless belt40, Fig. 5, 'which is a side elevation of the apparatus used in thisapplication of my invention, driven by any suitable means by rollersl 41and having a portion of they design that is to be impressed onthelcompleted roofing sten# ciled out in the belt, as shown in the pla'nview of a section of the belt. at Fig. .6, in its simplest formsconsistingmerely ofapertures 42 evenly spaced along the belt.

`d\spaced differently than the apertures 42 in the belt 40, and itisevidentthat any design may be similarly worked out, the belts '40 and40', and rollers 41 and 41 being driven at the same speed.

With this method I use a sheet ofwaterproof compound formed from amachine similar to A, Fig. 1, but having the unit D replaced by sets Gand H, and the mineral matter is deposited on the sheet 7 through theapertures 42 and 42 Fig. 6, one color; for instance, red, beingdeposited through the apertures 42, and a different color; for instance,blue, being deposited through the apertures 42', and Will be firmly.embedded at the respective points in the sheet 7 by the squeeze rollers44 and 44.

' It is not necessary to'attempt to drop the material directly intothese apertures during the continuous travel of the sheet 7, as it maybe deposited all over the inner surface of the belt 40 and 40', thesurplus being 'scraped and blown oil' after the rollers 44 and 44 haveembedded the mineral matter ers 46 and 46 respectively.-

of the machine A, Fig. 1, would of course be a sheet of roofing with redand blue disks 0f the size of the apertures in the belt and of athickness corresponding to the thickness of the belt spaced uniformlythroughout its length. I

It is evident that this allows waste mat ter to be collected from eachunit, and as The result of the sheet 7 passing through the sets G and Hduring the operationv the colors are not mixed this may again be A usedwithout loss.

- It is also evident that the sheet may be passed throu h a number ofunits similar 'to G and` H, so that the design.r may be amplified andthe entire surface of the sheet covered, if so desired.

In Fig. 18 I showa section of a belt stenoiled out at points 71, 72and'73, in such a manner that when the unit shinglesare cut .from astrip stenciled with this belt, and the unit shingles are formed inaccordance with my Patent No. 1,213,472, dated Jan uary 23, 1917, forshingles, the 'surfaces 71, 72 and 73 will be that portionofsiheunitshingles exposed to the Weather, andfthis portion .will have a mineralsurfacathereon, While the remaindersof each'shingle will 4be free fromfmineral surfacing, and this remainder of the shin fles will be thatportion not exposed to Le lweather, as fully shown in Fig. 26, which isa-section of a roof laid withunit shingles made in ac cordance with myco-pendingnapplication, Serial #71,3'12, from roofing having min- "eralsurfacing' stenciled thereon, in accordance`with Fig. 18.

i Similarly the stencil shown in the belt in Fig. is adapted .to form. asheet ofV prepared roofing having mineral surfacing on that portionexposed to the weather in .shingle strips. cut from such sheets, and

folded in accordance withl my copendmg' application, Serial #71,312, andas shown in Fig. 25, which is a section of a roof laid with such shinglestrips. Similarly, Fig. 9 discloses a stencil ada ted to be used inputting a mineral sur acing on a sheet of preparedv rooing'in suchmanner that unit' shingles cut' therefrom will have all of that ortionexposed to the Weather 'covered Wit a mineral surfacing, as bettershownin Fig. 24, which represents a por. tion of a roof laid with suchshinglesl 1n a similarl manner by replacing the unit D, machine A, Fig.1, with unit M, Fig. 20, I obtain the stenciling effect in4 a stilldiEerent manner, this latter construction being an' alternative to theone shown in Fig. 5, which is my preferred construction.

In the machine M, a pair of rollers`9i carry a stenciling belt -92similar to the stenciling belt4;O,Fig. 5, and a pair of rollers 93mounted inside of the stenciling belt 92, carry a second stenciling belt94, which corresponds to the stenciling belt 40', Fig. 5.

Similar to the 4construction disclosed in Fig. 5, a reservoir 95,deposits mineral surfacing matter on the larger belt, which is rolledlinto position by the rollers-96, and the surplus being scraped off bythe scraper 97.

It is evident that as the distance between i the rollers '9, Fig. l, maybe anyamount,

any number 'of stenciling belts may be combined, as shown in Fig. 20,'and any type of stencil Worked out through this method.

The application-of the water-proof sheet as applz'cal to roofinginsulation, sz'dfhtg, sheeting,damp courses fooa walls, etc.
